The invention provides a method for repairing sealing leakage of an integral fuel tank of an airplane, which is suitable for repairing sealing leakage of a binding surface, repairing sealing leakage outside a seam and repairing leakage of a rivet in the integral fuel tank of the airplane, and comprises the following steps of: determining a sealing leakage part of the integral fuel tank of the airplane; the sealing leakage part of the whole fuel tank of the airplane is subjected to local leakage sealing repair through a sealant, and the used sealant is a sealant compatible with a sealing system; and when the sealing leakage part of the integral fuel tank of the airplane is in local leakage, the failure sealant is removed before the local leakage sealing repair, the structure is not damaged, and when an oxide film on the surface of the structure is damaged, repair processing treatment is carried out. According to the leakage treatment method for the overall fuel tank of the airplane, the overall fuel tank of the airplane can be rapidly repaired, the airplane parking period is shortened, the treatment manufacturability is good, operation is convenient, the maintenance strategy is reasonable, and the attendance rate of the airplane is guaranteed to the maximum extent.
